How to scale a vector layer in QGIS?
In QGIS you can use the Affine functions for scaling vector features. In the Vector menu: And the dialog looks like this: If you enter 1.3 in both the “Scale X” and “Scale Y” boxes, then the layer (or just the selected feature (s) will be scaled up by 130%.
How to resize shapefile features proportionally in QGIS?
In QGIS (1.8.0-Lisboa) on Windows (OSGeo4W Install), how would you resize a feature proportionally? The only way I’ve found to do this is by hand using either the Freehand Editing (0.2.6) plugin or the Reshape Features button.
How to enlarge a polygon in QGIS 2.18.16?
I have a single polygon shapefile (EPSG: 3044) which I want to enlarge using QGIS 2.18.16. I tried to use the vector affine transformation plugin, but whenever I try to change the size of the polygon, the whole layer changes its position and shape.
How to prevent a polygon from drifting in QGIS?
In order to prevent your shape from “drifting”, you’ll need to derive the centroid first. Run Centroid, using input polygon_layer. Here’s an example, with the centroid labelled using the expression x ($geometry)||’ ‘||y ($geometry).
What are ” map units ” and ” decimal degrees ” in QGIS?
I am a newbie, I think I’m pretty resourceful, but I cannot figure out, or find out by searches, just what “map units” are in QGIS as compared to “decimal degrees”. For example I can only navigate by entering coordinates in the status bar with “map units” – decimal degrees do not seem to work?
How to increase the size of a feature in QGIS?
For example, I want to increase the features size by 130% so that you retain the shape of the feature but expand the area of the shape itself proportionally in all directions. In QGIS you can use the Affine functions for scaling vector features. In the Vector menu:
Are there affine transformations in QGIS 3.4?
Update (January 2019) for QGIS 3.4: Affine transformations can be are available through the Processing Toolbox with the GRASS algorithm v.transform. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
How does QGIS allow you to reproject data on the fly?
QGIS allows you to reproject data “on the fly”. What this means is that even if the data itself is in another CRS, QGIS can project it as if it were in a CRS of your choice. To enable “on the fly” projection, click on the CRS Status button in the Status Bar along the bottom of the QGIS window:
How is a multi page composition resized in QGIS?
In case of a multi-page composition, each page will be resized to include items in its area (left and right sides for all pages, plus top for the first page and bottom for the last page). Each resized page is exported to a separate file. The Crop to content dialog also allows to add some margins around the cropped bounds.
